refactor: Convert constants SentryTraceOrigins to Swift

[philprime]

📜 Description

Moves the global constants defined in SentryTraceOrigins.h to static constants in a Swift class

💡 Motivation and Context

• We want to migrate the code base to Swift over time
• We want the constants to be available in Swift without complicated setup
• It uses a @objcMembers class to make the static properties accessible from Objective-C.
• The current pattern uses the same syntax as Swift's enum which is not available in Objective-C. Eventually it will only be used from Swift files, and can be replaced with an enum without further code changes.

💚 How did you test it?

Unit tests

📝 Checklist

You have to check all boxes before merging:

• I added tests to verify the changes.
• No new PII added or SDK only sends newly added PII if sendDefaultPII is enabled.
• I updated the docs if needed.
• I updated the wizard if needed.
• Review from the native team if needed.
• No breaking change or entry added to the changelog.
• No breaking change for hybrid SDKs or communicated to hybrid SDKs.

🚨 Detected changes in high risk code 🚨

High-risk code can easily blow up and is hard to test. We had severe bugs in the past. Be extra careful when changing these files, and have an extra careful look at these:

• Sources/Sentry/SentryNetworkTracker.m

Also nice 👍🏻 Looks like this one will need a few fixes for tests, tho

I would like to keep the constants internal, please.
